2.0 on usb stick?

[Silverthorn]

You know, taking v1.9(c) on a usb stick is easy, you can play it on any computer. However, 2.0 needs this runtime environment. Is it somehow possible to "emulate" this environment, so that you don't have to install it on every comp (especially if they're not yours)? Like... manipulating the file path. The stuff that is being written into the system32-folder could be put into a temporary folder on your flash drive thus enabling you to play "lf2 portable"

It is possible at all?
